           Summary: [OOP] ICE when allocating a CLASS function-result
                    variable
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED

The following program fails with an ICE (with GCC 4.5 to 4.9):

test.f90: In function 'func2':
test.f90:13:0: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have function_type in gfc_class_vptr_get, at
